飞机活动面转角测量的方法探讨

真实飞机各部件的运动状态总是和理论状态存在差异,所以在飞机型号研制和试验试飞过程中,掌握飞机的实际运动状态是开展后续工作的基础,而由各种仪器测量结果来分析真实运动状态存在着许多困难。以某型号飞机的襟翼转角分析为例,从激光跟踪仪所测得的结果,分别通过圆模拟法和二面角法来分析襟翼在各卡位下的转角。并对两种方法进行详细的介绍和分析,以寻求合理的方法来消除测量误差、制造误差及结构变形对测量结果的影响,供后续工作的开展实施。

Discussion on the Method of Aircraft Moving Surface Rotation Angle Measurement

There always exists difference in moving conditions between the real parts and the theoretical parts. So in the process of aircraft design and flight tests, it's necessary to know the real moving condition of the aircraft parts. But there exists many problems in the analysis of the real moving condition by a variety of instruments. In this article, we will take the flap rotation angle measurement for example, to analyze the rotation angle using cycle simulation method and dihedral angle method with the data collected by laser tracker. We will introduce and analyze these two methods in detail, in order to search reasonable method to eliminate the influence of measure error,manufacture error and structure deformation to the final results, which will be used in the following working.
